Senior Materials Engineer

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

SR. MATERIALS ENGINEER, ELECTRONIC MATERIALS

SpaceX is leveraging its experience in building rockets and spacecraft to deploy Starlink, the world's most advanced broadband internet system. Starlink is the world's largest satellite constellation, providing fast, reliable internet to 10M+ users worldwide. We design, build, test, and operate all parts of the system - thousands of satellites, consumer receivers that allow users to connect within minutes of unboxing, and the software that brings it all together. We've only begun to scratch the surface of Starlink's potential global impact. As we continue to upgrade and expand the constellation, we are looking for the best-in-class engineers to join the team.
 
We are seeking a Sr. Materials Engineer to join our Bastrop, TX team, where we are advancing materials technologies to support the deployment of Starlink, the world's most advanced broadband internet system. The ideal candidate will bring deep expertise in semiconductor device physics and device fabrication, along with hands-on industry experience in at least one of the following domains—solar cell development, panel-level packaging, or printed circuit board (PCB) manufacturing—to drive material and process innovations across all three areas. This position requires a technical expert who delivers thoughtful leadership, collaborates with stakeholders to execute strategies aligned with Starlink's business objectives, budget, and priorities, while orchestrating end-to-end equipment and process development. You will push material and device performance limits to enable high-efficiency, reliable systems for space and terrestrial applications.

RESPONSIBILITIES:

• Lead the development and optimization of CVD recipes and device fabrication processes to boost solar cell efficiency.
• Own the full lifecycle of equipment specification, validation, and process development— including device modeling, characterization of performance metrics, and materials failure analysis.
• Build supply chains for wafers, gases, chemicals, and equipment for solar cell manufacturing. Define incoming acceptance criteria for materials (e.g. silicon wafers, conductive pastes).
• Address material and process challenges in panel-level packaging while spearheading the development of next-generation dielectric materials to improve packaging performance and scalability.
• Specify and implement in-process metrology tools for quality control. Design wafer-level test structures to evaluate material/electronic properties. Integrate simulation tools with experimental data to guide and drive targeted improvements via material or process changes.
